Abstract
The utility model relates to a cylinder bulging forming die. One end of a central guide pillar of the die is fixedly connected with a lower pressure plate; lower tapered wedge convex blocks are fixedly connected with a lower die plate; a pressure spring is arranged between the lower pressure plate and the lower die plate; the other end of the central guide pillar is provided with upper tapered wedge convex blocks which are fixed on an upper die plate; an upper pressure plate is flexibly connected with the upper die plate; a pressure spring is arranged between the upper pressure plate and the upper die plate; a bulging module is arranged between the upper pressure plate and the lower pressure plate; and a pressure spring is arranged on the external profile of the bulging module. The cylinder bulging forming die has the advantages of being high in guiding accuracy, guaranteeing consistency of the diameter of a cylinder, being capable of bulging after repeatedly rotating a steel cylinder, well guaranteeing the accuracy of products, being uniform in force distribution and stable and reliable and enabling the service life of the die to be improved.
Description
Technical field
The utility model relates to a kind of mould, especially a kind of cylinder expansion forming mould.
Background technology
In field of machining, there is all size steel cylinder to need expansion forming, at the machining accuracy height, when certain batch is arranged, must adopt the mould expansion forming.Generally can adopt expansion forming mould structure shown in Figure 1 in the actual production at present, this mould comprises several modules, the module circular distribution, but the interior profile that forms is taper and cooperates with the cone of axially-movable, when cone motion, outwards strut module, the outline of module carries out the application of force, expansion to cylinder to be processed.This expanding die is simple in structure, but can make processing precision of products low, and mould different parts degree of wear difference in using because of mould simultaneously makes steel cylinder two ends diameter and middle part diameter error bigger, and this is to cause error, and can influence die life.
Summary of the invention
The purpose of this utility model provides a kind of cylinder expansion forming mould, realizing satisfying the product required precision after the cylinder processing, in reducing to use to the wearing and tearing of mould, the service life of improving mould.
The technical solution of the utility model is, cylinder expansion forming mould comprises center guide pillar, the bulging module, epicone wedge jacking block, under bore the wedge jacking block, top board, lower platen, cope match-plate pattern, lower bolster, one end of center guide pillar is fixedlyed connected with lower platen, under bore the wedge jacking block and fixedly connected with lower bolster, be provided with compression spring between lower platen and the lower bolster, the other end of center guide pillar is provided with the epicone wedge jacking block that is fixed on the cope match-plate pattern, described top board and cope match-plate pattern flexibly connect and between be provided with compression spring, described epicone wedge jacking block can move along center guide pillar, epicone wedge jacking block is the identical taper of tapering with boring the wedge jacking block down, and the minor diameter direction of taper is relative; Between top board and lower platen, be provided with the bulging module, described bulging module is identical polylith and all flexibly connects with top board and lower platen, the interior profile of each bulging module respectively with epicone wedge jacking block and following awl wedge jacking block cone match, the outline of all bulging modules is provided with tension spring, and described tension spring is identical and two of being symmetrically distributed of parameter; Described compression spring is uniform a plurality of, and described bulging module is 6.
The utlity model has the high accuracy guiding, the characteristics of the synchronism of assurance expansion forming, reasonable Arrangement has been done in expansion forming power source simultaneously, at synchronously outside bulging of steel cylinder two ends while, guarantees the uniformity of drum diameter; In the bulging process, can rotate steel cylinder bulging more repeatedly, better guaranteed the product precision; Mould guiding accuracy height stressedly is evenly distributed reliable and stablely, and be improved die life.

Fig. 2 is the utility model mould structure schematic diagram.
The specific embodiment
As shown in the figure, cylinder expansion forming mould comprises center guide pillar 9, bulging module 10, epicone wedge jacking block 11, under bore wedge jacking block 8, top board 13, lower platen 7, cope match-plate pattern 14, lower bolster 5, one end of center guide pillar 9 is fixedlyed connected with lower platen 7, under bore wedge jacking block 8 and fixedly connected with lower bolster 5, be provided with compression spring 4 between lower platen 7 and the lower bolster 5, the other end of center guide pillar 9 is provided with the epicone wedge jacking block 11 that is fixed on the cope match-plate pattern 14, described top board 13 and cope match-plate pattern 14 flexibly connect and between be provided with compression spring 15, described epicone wedge jacking block 11 can move along center guide pillar 8, epicone wedge jacking block 11 is the identical taper of tapering with boring wedge jacking block 8 down, and the minor diameter direction of taper is relative; Between top board 13 and lower platen 7, be provided with bulging module 10, described bulging module 10 is identical polylith and all flexibly connects with top board 13 and lower platen 7, the interior profile of each bulging module 10 respectively with epicone wedge jacking block 11 and awl wedge jacking block 8 cone match down, the outline of all bulging modules 10 is provided with tension spring 12, and described tension spring 12 is identical and two of being symmetrically distributed of parameter; Described compression spring 5,12 is uniform a plurality of, and described bulging module 10 is 6.
The utility model is lifted away from top board and cope match-plate pattern in use, is inserted in steel cylinder to be processed, top board and cope match-plate pattern is closed again, and exerts pressure by punch press, carries out expansion forming, in the bulging process, need rotate steel cylinder bulging more repeatedly.
